What is and what is not electromagnetically induced transparency in whispering-gallery microcavities

There has been an increasing interest in all-optical analogues of electromagnetically induced transparency and Autler-Townes splitting. Despite the differences in their underlying physics, both electromagnetically induced transparency and Autler-Townes splitting are quantified by a transparency window in the absorption or transmission spectrum, which often leads to a confusion about its origin. While the transparency window in electromagnetically induced transparency is a result of Fano interference among different transition pathways, in Autler-Townes splitting it is the result of strong field-driven interactions leading to the splitting of energy levels. Being able to tell objectively whether an observed transparency window is because of electromagnetically induced transparency or Autler-Townes splitting is crucial for applications and for clarifying the physics involved. Here we demonstrate the pathways leading to electromagnetically induced transparency, Fano resonances and AutlerTownes splitting in coupled whispering-gallery-mode resonators. Moreover, we report the application of the Akaike Information Criterion discerning between all-optical analogues of electromagnetically induced transparency and Autler-Townes splitting and clarifying the transition between them.

“…However, the major challenge in realizing CROWs and using multiple resonators for dispersion engineering [7], [8] has been the fabrication of low-loss resonators with strict size tolerances. The problem is compounded when the resonators are weakly coupled because of the narrow linewidth of the coupled resonators.…”

Abstract-We present measurements of the transmission and dispersion properties of coupled-resonator optical waveguides (CROWs) consisting of weakly coupled polymer microring resonators. The fabrication and the measurement methods of the CROWs are discussed as well. The experimental results agree well with the theoretical loss, waveguide dispersion, group delay, group velocity, and group-velocity dispersion (GVD). The intrinsic quality factors of the microrings were about 1.5 × 10 4 to 1.8 × 10 4 , and group delays greater than 100 ps were measured with a GVD between −70 and 100 ps/(nm · resonator). With clear and simple spectral responses and without a need for the tuning of the resonators, the polymer microring CROWs demonstrate the practicability of using a large number of microresonators to control the propagation of optical waves.

“…These 1550 nm emissions are desired because they are used in the low loss transparency window of silica glass for optical telecommunications. The microspheres can be used, for example, as optical components in microphotonic circuits [21][22][23] or as multicolor light source micro-optical sensors. 24,25 A typical single mode lasing emission from a 55 m microsphere made in the tube furnace is shown in Fig.…”

Access to the full text of the published version may require a subscription. We report on the design of an electric tube furnace that can be used for the fabrication of doped glass microsphere lasers. The tube furnace has a short hot zone of length 133 mm and is based on a quartz tube design. Doped laser glass particles, specifically Er:Yb phosphate glass ͑IOG-2͒, of ϳ1 m diameter are blown into the furnace using a 60 ml syringe and microspheres ranging in size from 10 to 400 m are collected at the output of the tube furnace in a Petri dish. The furnace operates at a wall temperature of ϳ900°C and is capable of making microspheres from glasses with glass transition temperatures of at least 375°C. High quality ͑Q ϳ 10 5 ͒ whispering gallery modes have been excited within the microspheres by optically pumping at 978 nm via a tapered optical fiber. Rights
